A meta-study of athletic identity research in sport psychology: Current status and future directions
2015
ABSTRACTThe aim of this meta-study is to provide a critical synthesis of qualitative research on athletic identity in sport psychology. A total of 108 empirical studies were identified, including 63 quantitative studies, 40 qualitative studies, and five mixed methods studies. Qualitative and mixed methods studies were reviewed with the meta-study method, which involves a meta-analysis in terms of theoretical perspectives, methodologies, and findings. In our discussion we focus on evaluating and critiquing the current status of qualitative research on athletic identity and outlining recommendations for improving methodological rigor. It is concluded that both quantitative and qualitative stu…
Exogenous sources of regional industrial change
2017
The role of exogenous sources of new path development has been underplayed in the literature on regional industrial change so far. The aim of this article is to explore in a conceptual way under which conditions and in what ways non-local knowledge can lead to new path development in different regional innovation systems (RISs). We distinguish between organizationally thick and diversified RISs, thick and specialized RISs and thin RISs and argue that these types vary substantially in their needs for exogenous sources as well as in their capacities to attract and absorb knowledge generated elsewhere.
The measurement of populist attitudes: Testing cross-national scales using item response theory
2019
Recent research in the populism literature has devoted considerable efforts to the conceptualisation and examination of populism on the individual level, that is, populist attitudes. Despite rapid progress in the field, questions of adequate measurement and empirical evaluation of measures of populist attitudes remain scarce. Seeking to remedy these shortcomings, we apply a cross-national measurement model, using item response theory, to six established and two new populist indicators. Drawing on a cross-national survey (nine European countries, n = 18,368), we engage in a four-folded analysis. First, we examine the commonly used 6-item populism scale. Second, we expand the measurement wit…
Reciprocal relations between autonomous motivation from self-determination theory and social cognition constructs from the theory of planned behavior…
2020
Abstract Objectives The present study examined reciprocal relations between autonomous motivation from self-determination theory (SDT) and constructs from the theory of planned behavior (TPB) in a sport injury context. Methods The study adopted a three-wave longitudinal cross-lagged panel design. Physical education students in China (N = 4414; Mage = 14.42, SD = 1.75) completed self-report measures of autonomous motivation, attitude, subjective norm, and perceived behavioral control with respect to sport injury prevention at baseline (T1) and at two follow-up occasions one (T2) and three (T3) months later. Proposed reciprocal relations between autonomous motivation and the TPB constructs co…
Optimizing Query Perturbations to Enhance Shape Retrieval
2020
3D Shape retrieval algorithms use shape descriptors to identify shapes in a database that are the most similar to a given key shape, called the query. Many shape descriptors are known but none is perfect. Therefore, the common approach in building 3D Shape retrieval tools is to combine several descriptors with some fusion rule. This article proposes an orthogonal approach. The query is improved with a Genetic Algorithm. The latter makes evolve a population of perturbed copies of the query, called clones. The best clone is the closest to its closest shapes in the database, for a given shape descriptor. Experimental results show that improving the query also improves the precision and complet…
An Efficient Cooperative Smearing Technique for Degraded Historical Documents Images Segmentation
2020
Segmentation is one of the critical steps in historical document image analysis systems that determines the quality of the search, understanding, recognition and interpretation processes. It allows isolating the objects to be considered and separating the regions of interest (paragraphs, lines, words and characters) from other entities (figures, graphs, tables, etc.). This stage follows the thresholding, which aims to improve the quality of the document and to extract its background from its foreground, also for detecting and correcting the skew that leads to redress the document. Here, a hybrid method is proposed in order to locate words and characters in both handwritten and printed docu…
The moral work of becoming a professional
2021
Abstract In contemporary working life, art-based initiatives are increasingly used in organizational training and development. For artists, this has created new employment opportunities as creative entrepreneurs who provide specialist services for workplaces. In this article, we study the dynamics of such encounters through the narrated accounts of training professionals. Our data come from a professional mentoring program where the working pairs of artists and consultants shared stories about their customer projects. By using conversation analysis as a method, we analyze the way stories are interactionally accomplished in peer group sessions of the program. In particular, we analyze how pa…
Interventions of speakers of Polish and British parliaments in the light of politeness theory
2021
Abstract The present study attempts to analyze the interventions of Speakers of Polish and British Parliaments in the selected exchanges from 2018 to 2019 in terms of discourse-sensitive politeness theory advanced by Jonathan Culpeper. He proposes to use three types of impoliteness that affect three types of interlocutors’ faces via a range of impoliteness strategies. In the analyses we consider the linguistic, personal, and cultural as well as political context of the exchanges against the background of the unique, historically rooted institutional circumstances, with a special emphasis on the role of different physical contexts of respective Parliamentary chambers. We emphasize the discur…
The interpreter as a citizen diplomat
2019
Abstract The article presents a case of interpretation as a political activity during the Cold War. In the 1980s and 1990s, a grassroots citizen diplomacy movement was initiated by the Californian Esalen Institute, the center of the American Human Potential Movement. In and around its Soviet-American exchange program, numerous individuals, NGOs and organizations established personal relationships and professional exchange with citizens of the two super powers and travelled in both directions. Interpreters had a complex and crucial role in this exchange which was different from both the professional experience of conference and of communal interpreting.
An Illustration to Ælfric’s De temporibus anni in Ælfwine’s Prayerbook
2020
L'articolo esamina un diagramma contenuto nel manoscritto London, British Library, Cotton Titus D.xxvii+xxvi, generalmente noto come 'Ælfwine’s Prayerbook'. Il diagramma, che si trova al fol. 21 v , è stato in genere interpretato come una rota incompleta, o delle maree o dei venti (dal momento che contiene solo 4 dei canonici 12 venti della tradizione scientifica medievale). Una analisi comparativa e dettagliata delle caratteristiche del diagramma, tuttavia, mostra come l'ipotesi della rota delle maree sia da rigettare in favore della teoria di una rota ventorum. Inoltre, l'analisi dei testi contenuti nel manoscritto rivela una stretta connessione tra il diagramma e il De temporibus anni di…
